Objective: To associate anthropometric indicators and blood pressure with waist-to-height ratio in school students. Methods: Cross-sectional study conducted with 342 school students aged 6-11 years from a municipality of Rio Grande do Sul, Brazil, with data collected from March to November of 2014 by measuring weight, height, systolic and diastolic blood pressure (SBP/DBP), waist circumference (WC) and the waist-to-height ratio (WHtR). T-student and Qui-squared tests were used with significance level set at 5% (p≤0.05). Results: Of all students, 54.4% (n=186) were female, 32.7% (n=112) were overweight and 5% (n=17) were obese according to BMI classification; 11.1% (n=38) were pre-hypertensive and 5% (n=17) had stage I hypertension according to the overall SBP/DPB classification; 37.1% (n=127) had an increased WC and 23.4% (n=80) had an increased WHtR. There were no students with stage II and III hypertension in the sample. Thinness and normal weight (p≤0.01), normal SBP and DPB (p≤0.01) and normal WC (p≤0.01) were significantly associated with normal WHtR whereas overweight and obesity (p≤0.01), pre-hypertension (p≤0.01) and increased WC (p≤0.01) were significantly associated with increased WHtR. Conclusion: The male gender presented significantly increased anthropometric measures than the female gender. Thinness, normal weight, blood pressure and waist circumference were associated with normal waist-to-height ratio (WHtR) whereas overweight, obesity, prehypertension and increased WC (p≤0.01) were associated with increased WHtR.
